CONTINUOUS OIL-PRESS.

Specification of Letters Patent.

Application led May 1, 1911.

To all whom it'mwy concern:

Be it known that4 we, FRANK A. BLAIN and CLYVE D. HELM, citizens of theUnited States, residing at Fort Worth, in the county of Tarrant andState of Texas, have invented certain new and useful Improvements inContinuous Oil-Presses, of which the following is a specication.

This invention relates to oil presses and more particularly to rollerpresses which are provided with a continuous feed, and the object is toprovide presses for extracting oil from such material as cotton seed,linseed, pea-nuts and other nuts, beans, grains, and to press juicesyfrom fruits, and to provide presses which have a continuous feed whichis accomplished mechanically and which press the oil or juice from thematerial by means of endless traveling aprons or chain belts. With suchpresses the large force of laborers who are usually employed forpreparing the material for the presses is dispensed with as well as thedanger to such employees and the pressing is done in much less time thanis required where the material is prepared manually for the presses. Thefeeding is continuous and the pressing is continuous. l

Other objects and advantages will be fully explained in the followingdescription and the invention will be more particularly pointed out inthe claims.

Reference is had to the accompanying drawings which form a part of thisapplication and specification.

Figure 1 is a side elevation of the press. Fig. 2 is a cross-sectiontaken on the line x of Fig. 1. Fig. 3 is a portion of the lowercompression rollers and the gearing for driving the same, shown in adiagrammatic plan view. Fig. 4 is a plan view of a portion of the lowerapron or chain belt. Fig. 5 is a vertical cross-section of the travelingaprons or chain belts. Fig. 6 is.a side elevation of a portion of thelower traveling apron.

Similar characters of reference are used to indicate the samerpartsthroughout the several views.

The improved press is provided with a frame consisting of pedestalsV 1and lower side bars 2 and upper side bars 3. The upper beams 3 and thelower beams 2 are held in operative relation by the tie bars 4 and 5with suitable nuts 6 and caps 7.

The beams 2 are held properly spaced by tie rods 8. The beams or bars 2and 3 are set at an incline, as shown in Fig. 2, so that the oil willnot follow the pressed cake out of the machine, but escape downwardlyinto a pan or receiver 54 whence it may be drawn off through a cock 55.The material to be pressed is carried by chain belts or apronshereinafter described and the chains can be made to run more or lessclosely'v together by caps 7 and nuts rand the vchain belts will be madeto approach each other more closely toward the delivery end of themachine so that the pressing will be done progressively.

Lower compression rollers 9, 10, and 11 are journaled in fixed bearings12 attached to beams 2 and these rollers have cogs 13 on each vendthereof which mesh with pinions 14 which are provided with bearings 15attached to beams 12. A is providedfor the rollers 9, 10, and 11. Apower pulley or drive wheel 16 is fixedly mounted on a power shaft 17. Apinion 18 is rigid with wheel 16 and drives a cog wheel 19,. A pinion20' is rigid with the'cog wheel 19 and the cog wheel 19 and the pinion20 are rigid with shaft 21. Pinion 2O drives a cog wheel 22 and cogwheel 22 drives a pinion 23 which is rigid therewith. The pinion 23 andcog wheel 22 are loosely mounted on the shaft 24.l Pinion 23 drives acog wheel 25 which is rigid with shaft 26. The shaft 2 6 drives pinion14 and pinion 14 drives cog wheels 13 which drive rollers 10 and 11. Cogwheel 13 of roller 10 drives pinion 14 and pinion 14 drives cog wheel 13and roller 9.

A traveling apron or chain belt 27 is driven by the cog wheels 13 and bya drum 28, the drum 28 being driven by the shaft 17. An idle drum 29 ismounted on a shaft 30 to support the chain belt 27 at the receiving endof the machine. The chain is moved continuously during operation overthe rollers 9, 10, and 11. The chain belt 27 is constructed to form abed for receiving material and holding the same' thereon while thematerial is being pressed by the rollers. The chain is constructed ofbars 32 which are dovetailed into each other and the dovetailed portionsare hingedly connected together by rods 31. The outer ends of the barshave upwardly projecting flanges 32 to form sides of the apron toprevent escape of material laterally. Cog teeth 33 positive drive formracks on each side of the chain belt to be engaged by the cog wheels 13whereby the chain belt is driven. The oil or juice will escapedownwardly through the joints of the bars which form the chain belt. Asheet of camels hair cloth 34 may be spread on the chain 27 for betterstraining of the oil or juice.

Rollers 35, 36, and 37 similar to rollers 9, l0, and l1 are mountedabove the rollers 9, 10, and 1l for compressing material which is beingcarried on chain 27. These rollers are journaled in bearings 38 whichare fixed on beams 3. Means are provided for driving these rollerspositively. Roller 37 is driven from the shaft 24 by means of spur gearwheels 39 and 40. The rollers 35, 36, and 37 each have cog wheels 41formed on each end thereof, and pinions 42 mesh with these cog wheels,so that the series of gearing may be driven from shaft 43. The cogwheels 41 drive a chain 45, similar to chain 27. Idle drums 46 aremounted on the beams 3 by bearings 38 for maintaining the position ofthc chain 45 during operation. The chain- 45 has racks 47 on the sidesthereof to be engaged by the cog wheels 4l. The parts of the chains 27and 45 adjacent to each other run substantially in the same direction. Asheet of camels hair cloth 50 may be placed under the chain 45.

Means are provided for applying pressure to the rollers and consequentlyto the chains 27 and 45. A hydraulic cylinder 43 is mounted above thebeams 3 for pressing thereon. A piston 49 operates in the cylinder 48.The hydraulic pressure will take effect also on the cap 7 and theconsequence is that the beams 2 and the beams 3 are drawn toward eachother, and chains 27 and 45 are pressed toward each other.

Material 50 is fed to the chains 27 and 45 through a hopper 51 and chute52 to the lower chain belt 27. The oil or juice is pressed out of thematerial during its passage between the chains. The pressed cake 53 isdelivered in sheets by the chain belts 27 and 45 and may be gathered inany suitable manner. Additional idle drums 54 may be placed between thecompression rollers to support traveling aprons 27 and 45. An agitator55 may be used in the hopper 5l to aid in distributing stock to theapron 27.

Having fully described our invention, what we claim as new and desire tosecure by Letters Patent, is,-
